Ungarische Zigeunerweisen Konzert im ungarischen Stil Hungarian Gypsy Melodies Concerto in the Hungarian Style is a single-movement work for piano and orchestra of about 17 minutes` duration by Sophie Menter renowned 19th-century pianist and Franz Liszt`s favourite female student. The work was written in 1885 with possible help from Liszt orchestrated by Pyotr Ilyich Tchaikovsky in 1892 and first performed by Menter with Tchaikovsky conducting in 1893.
The work is listed in Liszt`s catalogue as S.714 recently renumbered as S.126a on account of his possible involvement. It is not known whether Tchaikovsky played any part in the actual composition but towards the coda there is a harmonic sequence very familiar from Tchaikovsky`s concertos.
